15-Second summary

OpenCTI consolidates structured threat intelligence into a connected knowledge graph, but getting raw data structured, filtered, and formatted as STIX is the hard part. That's exactly what Feedly does. Feedly's AI monitors thousands of open-source channels, extracts key entities, maps relationships, and delivers clean STIX 2.1 intelligence scoped to your priority intelligence requirements.

With Feedly Threat Intelligence connected to OpenCTI, you can:

• Automatically populate your knowledge graph with relevant, structured intelligence from thousands of open-source channels.
• Start investigations with rich context; every entity is enriched with threat actors, TTPs, malware, CVEs, IoCs, and their relationships.
• Turn raw reports into ready-to-ingest STIX structures, ready for OpenCTI to ingest without cleanup or reformatting.

If you've invested in OpenCTI, Feedly Threat Intelligence helps you turn it into a knowledge graph that's ready for work.

A knowledge graph is only as good as what flows into it

OpenCTI gives CTI teams a powerful foundation for organizing, correlating, and operationalizing threat intelligence. But the platform doesn't collect intelligence on its own. To get the most out of it, teams need a reliable way to feed it with high-quality, relevant data, consistently and at scale.

Most teams rely on IoC-heavy commercial feeds that deliver volume without narrative context, leaving threat actor profiles thin and TTP coverage patchy. Analysts make up the difference manually: reading blogs, pulling reports, and copying data into the platform. Collection consumes hours that should be going toward analysis.

The result is a team spending more time on data management to feed the knowledge graph, than actual analysis.

Feedly Threat Intelligence automates the collection, processing and filtering layers. It continuously monitors thousands of open-source channels and uses AI to extract, structure, and deliver intelligence directly into OpenCTI, so your knowledge graph reflects the current threat landscape without requiring your analysts to build it manually.

Use AI Feeds to focus on what's actually relevant

Not all open-source intelligence is relevant to your organization. Feedly's AI Feeds solve the signal-to-noise problem before anything reaches OpenCTI.

AI Feeds are continuously updated streams of intelligence from over 10,000 open sources, filtered to your organization's specific threat profile: the threat actors targeting your sector, the malware families relevant to your tech stack, and the vulnerabilities that matter to your infrastructure.

You can also define your own trusted sources (specific blogs, vendor advisories, government feeds, or ISACs your team already relies on) and pull structured intelligence exclusively from those channels. This gives you full control over provenance, so your knowledge graph reflects the sources your analysts actually trust.

You can organize AI Feeds or Folders by intel requirements, and the connector continuously pulls from those curated streams. What flows into OpenCTI is curated intelligence scoped to what your team is actually tracking.

Feedly AI Models and the Threat Graph extract and enrich threat data

Feedly's AI Models automatically identify key entities within each article: IoCs (IPs, domains, hashes, URLs, email addresses, and registry keys), CVEs, malware families, threat actors, TTPs, cyberattacks, etc.

The Threat Graph maps the relationships between extracted entities: which threat actor is using which malware, which CVE is being exploited in which campaign, which TTPs are associated with which intrusion set. These relationships are built from the source reporting itself, preserving the analytical context that makes intelligence meaningful.

By the time intelligence leaves Feedly, it's no longer unstructured text. It's a set of connected entities with documented relationships, ready to enrich your knowledge graph rather than just add to it.

Structured for OpenCTI: STIX 2.1 out of the box

OpenCTI is built natively on the STIX 2.1 standard, and so is Feedly's output.

Every piece of intelligence the connector delivers is formatted as a STIX 2.1 bundle: threat actors, malware, TTPs, indicators, vulnerabilities, and the relationships between them are all expressed as proper STIX objects. They map directly to OpenCTI's data model without transformation or cleanup on your end.

This means the intelligence that lands in your knowledge graph is immediately usable, correctly typed, correctly linked, and ready for analysts to pivot on.

What it looks like in OpenCTI

Once the connector is running, Feedly intelligence appears in OpenCTI as fully structured reports, each one linked to the entities Feedly extracted, with relationships already mapped in the knowledge graph.

Analysts can pivot directly from a Feedly report to the threat actor profile, explore related malware or campaigns, and correlate Feedly-sourced indicators against internal data, all within OpenCTI's graph interface, without re-entering a single data point.

Conclusion

Feedly Threat Intelligence and OpenCTI are built for each other: one collects and structures intelligence from the open web, the other organizes and operationalizes it. Together, they replace a slow, manual collection process with a continuous, automated intelligence pipeline, from open-source data to a knowledge graph to analyst action.

If you've built an OpenCTI deployment and want to keep it current without burning analyst hours on collection, Feedly is the intelligence source that makes it work.
